Among these 35 miRNAs, 16 miRNAs, whose downregulation associates with a worse prognosis of ovarian cancer patients33, have been analyzed revealing that miR-200b/c and miR-429 could be putative regulatory miRNAs of both ETAR and ZEB1, as depicted in the Venn diagram (Fig. 2a). The gene discussed is EDNRA; the disease is ovarian cancer.
